When you are back at work:
Open the app and click on Working.
The app will send an SMS or an Email to HR that registers you as working.
That's it, go and work.
The idea is that there is quite a lot of admin to do by you when you get sick.
If you get very ill, it should be easy for you to report this, and concentrate on getting well.
If you have a migraine, or a really bad cold, it is hard to do that admin.
ESA will do this for you.
Note, that not all companies has automatic reporting systems for this, but it can be used manually as well.
All this depends on the employer.
